formatting a table

I made this table and I am having trouble formatting it. I want all the decimals in each column to line up and have each value to 2 decimal plays but because of the negatives and different number of values before the table it screws everything up. Whats a better way to format this? Thanks. P.S. Am I even using meshgrid correctly? It is a homework problem and I need to use meshgrid and vectorized calculations. My values are all right just not sure if making the variables x1, x2, x3 is necessary.

clear
t=0:10;
v=[10, -10, 20];
a=[2, 4, -6];

[V,A,T]=meshgrid(v,a,t);
x=V.*T+0.5.*A.*T.^2;
x1=x(1,1,:);
x2=x(2,2,:);
x3=x(3,3,:);

fprintf('\n');
fprintf('------------------------------------\n');
fprintf('        v = 10    v = -10    v = 20\n');
fprintf('t       a = 2     a = 4      a = -6\n');
fprintf('------------------------------------\n');
for k=(1:11),
  fprintf('%2d      %3.2f      %3.2f      %3.2f\n', t(k), x1(k), x2(k), x3(k));
end

Instead of using a bunch of spaces and then %3.2f, use no spaces and after the % put the total number of columns the field should occupy including spaces. Continue to use the .2f part.

For example,

fprintf('%2d%15.2f%15.2f%15.2f\n', ....)
